Beschreibung description
Die vorliegende Erfindung betrifft ein Verfahren zur Erzeugung einer keramikähnlichen Oberfläche, ein Verfahren für die Anpassung eines Gasphasenabscheideverfahrens für die Erzeugung einer keramikähnlichen Oberfläche sowie eine entsprechende Verwendung dieser Verfahren für die Herstellung eines mobilen Bauteils. The present invention relates to a method for producing a ceramic-like surface, a method for the adaptation of a gas phase deposition method for the production of a ceramic-like surface and a corresponding use of these methods for the production of a mobile component.

Bei Fahrzeugen wird inzwischen neben metallisierenden Beschichtungen auch keramisches Material als Dekormaterial eingesetzt. In der Einsatzsituation innerhalb eines Fahrzeugs ist Keramik hinsichtlich seiner mechanischen Eigenschaften gut verwendbar. Jedoch ist es bisher nicht möglich, Keramik auch bei mobilen Bauteilen einzusetzen, da die mechanischen Eigenschaften von Keramik bzw. Keramikmaterial den Anforderungen an mobile Bauteile nicht genügen. Insbesondere ist hierbei die Fallgefahr zu erwähnen, welche hohe Anforderungen an Duktilität und mechanische Stabilität des entsprechenden Materials der Oberfläche stellt. Würde bei einem solchen mobilen Bauteil, z. B. einem Mobiltelefon oder einer Fernbedienung eines Fahrzeugs, Keramik als Werkstoff eingesetzt sein, so bestünde die Gefahr des Abplatzens bzw. Beschädigens dieser Bauteile oder der Oberfläche, wenn das mobile Bauteil herunterfällt. Auch die Dauerstabilität im Einsatz in der Hand eines Benutzers bzw. in der Hosentasche oder anderen Aufbewahrungsorten ist bei keramischem Material nicht gegeben. Im Rahmen der vorliegenden Erfindung werden die Begriffe Keramik und keramisches Material synonym verwendet. Es ist Aufgabe der vorliegenden Erfindung, die voranstehend beschriebenen Nachteile zu beheben. Insbesondere ist es Aufgabe der vorliegenden Erfindung, auch bei hohen mechanischen Anforderungen, wie sie bei mobilen Bauteilen auftreten, zumindest eine sensorische Eigenschaften von Keramik auf der Oberfläche dieses Bauteils zur Verfügung stellen zu können. Darüber hinaus sollen Kosten und Herstellaufwand reduziert werden. In vehicles, in addition to metallizing coatings and ceramic material is now used as a decorative material. In the situation of use within a vehicle, ceramic is easy to use in terms of its mechanical properties. However, it has not been possible to use ceramic in mobile components, since the mechanical properties of ceramic or ceramic material does not meet the requirements of mobile components. In particular, the case risk is to mention, which makes high demands on ductility and mechanical stability of the corresponding material of the surface. Would be in such a mobile component, for. As a mobile phone or a remote control of a vehicle, ceramics used as a material, so there would be a risk of chipping or damaging these components or the surface when the mobile component drops. The durability in use in the hands of a user or in the pocket or other storage locations is not given in ceramic material. In the context of the present invention, the terms ceramic and ceramic material are used synonymously. It is an object of the present invention to overcome the disadvantages described above. In particular, it is an object of the present invention to be able to provide at least one sensory properties of ceramic on the surface of this component, even with high mechanical requirements, as they occur in mobile components. In addition, costs and manufacturing costs should be reduced.
